Study of N-1L Corrosion of Carbon Steel in Acidic Desulfurizer Performance

Abstract:

This paper uses a metal hung weight loss method, acidic ionic liquid desulfurizer as the media, by adding different inhibitor (Polyethylene Glycol, SDBS, Functional ionic liquids), contrast to carbon steel corrosion in the absence of inhibitor, understanding of their respective inhibition effect. In the experiment, the carbon steel material, different kinds and concentrations of the inhibitor in the medium, the corrosion rate measured by weight loss method. Contrast to the blank experiment the inhibition rate can be calculated. The experiment proved that the inhibition effect of several inhibitor at room temperature, and calculate their respective optimal concentration. The experiment also investigated the compound of several corrosion inhibition synergies, confirm the good corrosion inhibiting effect of polyethylene Glycol and SDBS complex, the inhibition rate reached 69.2%.Excellent inhibition effect of the ionic liquid corrosion inhibitor and the inhibition rate reached 88.3%, showing a clear advantage.
